SPECIFICATION forming part of Letters JPatent No. 433,571, dated August5, 1890. Application filed April 19, 1890. Serial No, 348,631. (Nomodelt) To all whom it may concern:

Be it known that I, AUGUST KLEIN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain. new and useful Improvements in Rail-Joints; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in railway-rails of aconstruction adapted to effect a secure joint at their meeting ends, andit will be fully understood from the following description and claim,taken in connection with the accompanying drawings, in which Figure l isa longitudinal elevation of two railway-rails embodying my improvementsin a joined position. Fig. 2 is a similar view of the same, a portionbeing broken away at their junction to show the manner of construction.Fig. 3 is a perspective view of the end of rail carrying the dovetailprojecting tongue and the recess for the reception of the projecting lugof adjacent rail, and Fig. 4 is a perspective view of the end of railprovided with the dovetail recess for the reception of the dovetailtongue of adjacent rail and carrying the lug projection to take into therecess of opposite rail.

It will be understood from the following description that myimprovements are of a construction such as may be formed with the railat the time of manufacture, or in rails at present in use, as they in nomanner alter the general construction of the same.

In carrying out my invention I take a railway-rail, which may be of theordinary construction, and form in the bottom thereof at one of its endsa dovetail groove or recess B, for the reception of a tenontongueprojecting from the bottom of the end of an adjacent rail. This dovetailgroove or recess B is of a length and width in proportion to the size ofthe rail, and it is obvious that by its being formed at the pointdescribed the rail is in no manner weakened, but rather strength ened,for when the dovetail tenon or tongue is in position in the groove ittakes the place of the displaced metal thereof, and by breaking thejoint between the two rails affords a juncture thereof capable ofresisting lateral eration takes into a similarlysituated recess oropening in the end of the rail carrying the projecting tongue. At. theopposite end of the rail from the one described, and which is betterillustrated in-Fig. 3, I form a projecting tongue or tenon D, ofdovetail configuration, which is of a size to take-into the dovetailrecess of the adjacent meeting rail, as has been described. Thisdovetail tongue projection may be either cast integral with the rail orsecurely fixed therein; but the former construction is preferable, as itmakes a construction of greater strength and renders the manufacture ofthe rail more simple.

E indicates the recess or opening for the reception of the lug G, whichoccupies a position in one end of the rail similar to that which the lugoccupies upon the other.

It will be obvious that by having the projecting dovetail tongue and therecess upon one end of the rail and the dovetail recess and theprojecting lug upon the other end, when the opposite ends of two railsare put together a strong juncture will be effected which will preventlateral spreading of the rails by reason of the jointbetween the twobeing broken, and it will also be observed that the rails may be quicklyput together and secured in a true line without inconvenience,fish-plates being dispensed with, if desired.

Having described my invention, what I claim is- The combination, with arailway-rail, of the dovetail groove formed in the bottom thereof at oneend, the dovetail projection extending from the opposite end at thebottom thereof,

the stud or lug projecting from the T portion of the end having thedovetail groove, and the recess formed in the T portion above theclovetail projection, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
